Hi all,
I have been snooping around for a bit now and have extracted some good info from the majority of you guys - of which I am grateful.

Being out of the loop in terms of PC building for the last 4 years means I've had to catch back up.

Anyway, been looking at upgrading my machine in the new year, but money looks a bit tight at the moment - cant quite justify a complete build. So thinking of whacking in a new graphics card. Originally thinking about a 5850 but with the lack of supply I've seen that the 5770 in crossfire is as good if not better.

I am thinking about getting one 5770 for the time being and then a second to crossfire in the new year once I justify my new build.
Currently running an E6600 @ stock w/Scythe Mugen cooler so room for OC if I can be arsed! lol
4x 512mb cheapy sticks of memory @ 5300 I think (had some issues with my xms2 memory - temporary fix, was going to replace but DDR2 memory is stupidly expensive!)
P5W DH Deluxe
X1900XT 256mb
Enermax Liberty 500w/620w

Any ideas, opinions etc are welcomed...

..really I'm just looking for someone to agree with my decision haha
 
what hes says is very true 1 of them is ok but in crossfire they really do come into there own. Im sending mine back though as mine have the 2D crash problem that a lot users have shame.
 
well its 500w really but on the box it says SLI 500w/620w

I assume that means there is an extra 120w for the second PCIE power connector

I doubt that. Are you sure the box isn't a generic one that is used for both liberty PSU's? Either way 500w should be enough for your system+Xfire'ed 5770.
 
Yeah I bought 2 of them for crossfire and stupidly bought x16/x4 mobo so new board next week maybe I will see more benefit of them. Although they very good at the minute too defo worth buying .

Could be but its in smaller text in the corner under the large image that states its SLI compatible.

500w should be more than enough I would have thought, but just wanted to make sure

I think I read somewhere that when I crossfire/SLI on my board it will bring both PCIe slots down to x8

Cheers all

Wow, thats a damn good review there. What suprised me is that even at PCI-E 2.0 x1 speed still returned very playable framrates in the games they tested.

Im wondering if i should slot this GTX260 i have in now into the x4 slot to see the difference for myself ;)

Yep 8x 8x is all that's needed really but 4x does fine and even a boost with 1x madness, looks like they improved the scaling with the 5 series

Your p55 will be 8x 8x surely?

On a PCI-E 2.0 board though that isn't it, as a 4x slot will be like 8x won't it, where as the older PCI-E 1.0-1.1 will be 4x, so be more of a hit ??

Yea 8x 8x 2.0 = PCI-E 1.1 16x 16x

I think the 5 series communicate more through the Xfire bridge though?

Yeah but Takens not on PCI-E 2.0, hes on P35 chipset, so hes running his 2nd card at 4x, which is a big hit on performance from what i remember, as when those boards came out, im sure everyone was saying they no good for Xfire as the 2nd slot only runs at 4x, where as on PCI-E 2.0, be like the old 8x, so you would only lose about 4% then (which that review shows).
